BALL-BEARING.

Specification of Letters Patent.

Patented. April 13, 1909.

To all whom it may concern:

Be it known that I, SCOTT R. COPPINS, a citizen of the United States, residing at Princeton, in the county of Bureau and State of Illinois, -ha e invented certain new and useful Improvements in Ball-Bearings; and I do hereb declare the following to be a full, clear, an exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in ball bearings and more particularly to that class adapted to be used in connection with vehicle spindles and my oh- I ject is to provide a device of this class which may be readil a lied to an make of s indles, boxing ahd hafting. y p

further object is to provide a' device of this class which will consist of but few parts.

A still further object is to so construct the parts of the bearing that the balls will be prevented from movin toward the sides of the races and thewheel held against lateral movement.

A still further object is to provide a ring and cup that may be readily adjusted to compensate for wear.

Other objects and advantages will be here- I inafter referred to andsnore particularly pointed out in the claim.

In the accom anying drawings which are made a part of t 1is a plication, Figure 1 is a longitudinal sectionalview through a boxing and bearings mounted therein, the same being shown as a plied to use upon a spindle. Fig. 2 is an en elevation of a spindle showing m improved bearings mounted thereon.

Fig. 3 is a transverse sectional view through one of the bearings, as seen from line 33 F 1, and, Fig. 4 is a longitudinal sectional View through one of the bearings showing the same on an enlarged scale and employing a three point bearing.

Referring to the drawings in which similar reference numerals designate corresponding .parts throughout the several views, 1 indicates a spindle which may be of the usual or any preferred form and particularly of that class used in connection with buggies or light vehicles around which is adapted to be disposed a boxing or female section 2, the inner end of the boxing being rovided with an enlarged portion forming a ousinglS. The

55 opposite end of the boxmg or female part 2 is adapted to receive a male part or collar 4 formed integral with a similar housing 5, the housing 5 being of less diameter than the housing 3 the female part being interiorly threaded to receive the threaded end of the male part 4. Disposed around the inner and outer ends of the spindle 1 and within the housings 3 and 5 are my improved form of bearings comprising rings 6, each of said rings being provided with circular races 7 and 8 in which are disposed a plurality of bearing balls 9. The races 8 around the rings 6 are of greater depth than the races 7 so that the balls 9 Within the races 8 will run on a path of less diameter than will the balls in the races 7. In order to hold the balls within their respective races and to provide a bearing surface therefor, I have provided cups 10 which are stepped or provided with gradations on their inner surfaces to form.

shoulders or bearing points lllarid 12 which are adapted to engage the bearing balls 9 and hold the same withintheir respective races.

By disposing the inner tier of bearing balls lower than the outer tier and stepping or gradating the cups as shown, it w be seen-thafth'e'cups can be readily introduced over the rings and balls contained thereon. As soon as the bearing points upon the cups have been directed into engagement with the balls in the races, the cups are secured in position thereover by disposing a split ring or the like I3 within a channel 14 formed in one end of the cups 10 thereby securely locking the cups around the rings and into engagement with the bearing balls carried thereby. The cups 10 are so constructed that they snugly fit within the housings 3 and 5-respectively, while the rings 6 are provided with openings "so that they snugly fit u on their respective ends of the spindle so t at when the wheel is rotated the rings-will remain stationary u on the spindle and the washer 17, thenut 15 being first'disposed upon the threaded end. 18 of the spindle after which the locking Washer 17 is disposed in position around the threaded end 18 and against the outer face of the nut 15 when the nut 16 is turned upon the threaded end 18 and the locking washer secured between the will result in directing the boxing inwardly two nuts. The nut 15 may also be employed for taking up'the wear of the rings and cups as it will be seen that by directing the nut against the end of the outer ring 6 said ring-may be pushed longitudinally on the spindle which and disposing the bearing points of the two cu" s a ainst the balls.

n Fig. 1 'of the drawing I have shown the bearings as employing but two races 'wl1ile in--Fig. l of the drawing I have shown the bearings provided with three races and it will be readily understood that by increasing 1 the length of the ringsand'cups one or more races may be provided for, thereby enabling me to construct a bearing 01' the proper dimensions to be used in connection with Va.- rious sizes of vehicles. In constructing the hearings in tliis manner, it will beseen that the same can be constructed in sets and'readily applied to the hub of the wheel even by those not skilled in the art. 1 What I claim is:

The combination of anaxle, a boxing receiving said axle and having a bore of such diameter as to provide an annular space therebetween and said axle for rotation out of contact therewith, said boxing having an annular enlargement at one end i'orming a housing, alike housing arranged at the opposite end of said boxing and having screw threaded connection therewith and otherwise being a structural counterpart of the first-referred to housing or enlargement; ring-members snugly encompassing said axle, within said housings, and stationary thereon, said ringn1en1bers having series of annular'pernnetrlc grooves, cups oi greater diameter than, and encircl ng said rings,

within said housings, and provided with internal annular-stepped surfaces opposed to the grooves of said rings, balls bearing in said grooves and, against the shoulders formed by said stepped surfaces, and split rings interposed between the aforesaid rings and said on s, with one edge-of each splitr ng rece1ve( by a groove in each cup,- near-
